poptop funny log messages

[jromero at romero3000.com]

Running PopTop in test server and it seems to be working well, except the
logs are replete with error messages like:

-------------------------------------

 real ACCMs!

has anyone encountered this before??? the pptp service is working fine
but I would like to know if this is a serious problem.
